HOT SPOT TEMPERATURE CALCULATION
with
where
Due to the design of the capacitor and its technology, the
thermal impedance between the terminations and the core
of the capacitor is low, it is necessary to take care that
the capacitor is never overheated by use of wrongly sized
connections.
Do not use the capacitor as a heat sink.
Due to the complexity of the IGBT / capacitor thermal
exchanges, we recommend that thermal measurements
shall be made on the different components. We would be
pleased to advise you on specific problems.
WORKING TEMPERATURE
(according to the power to be dissipated) -40°C to +85°C
